Did you not see my 2 posts directed to you based on your oringinal message. I passed on some information for possible availability with guides in Rome and Sorrento. As far as Florence goes there might be room. I have hired a private guide for my husband and myself. He has a car that he says fit 4 comfortably but I am not certain. If you are interested let me know ASAP as we leave on Friday earlu A.M. We have hired a guide for Bacelona on May 9, we are staying 2 extra nights, and if you are interested please let me know. At this point the tour is only for my husband and myself.
The guides we have hired in Marseille and Monaco have no more space.
If you respond soon and let me know what you might like I will try to get you the information. On the ship we are in cabin 8045.

At the present time I have a possible opening for a Florence excursion and an excursion if you are staying in Barcelona post cruise on May 9th. As I stated in my previous answer I suggest that you contact the referrals I have mentioned. I do not know what openings Doreen has since we are not sharing every excursion.
If you are interested in Barcelona or Florence, let me know ASAP. We are leaving early Friday morning.
